Using a line generator

D3 line generator is probably one of the most versatile generators. Though it is called a "line" generator, it has little to do with the svg:line element. In contrast, it is implemented using the svg:path element. Like svg:path, D3 line generator is so flexible that you can effectively draw any shape using line alone, however, to make your life easier, D3 also provides other more specialized shape generators, which will be covered in later recipes in this chapter. In this recipe, we will draw multiple data-driven lines using the d3.svg.line generator.

How to do it...

Now, let's see the line generator in action:

<script type="text/javascript">
    var width = 500,
        height = 500,
        margin = 50,
        x = d3.scale.linear() // <-A
            .domain([0, 10])
            .range([margin, width - margin...
